In this article, we argue that party-system polarization and subjective perceptions of ideological party differences are conceptually and empirically distinct phenomena that affect electoral participation differently. Looking at 84 elections worldwide, we show that party-system polarization, and the sharp conflicts associated with it, depresses turnout because many citizens are put off by extreme party positions and unrewarding polemics. By contrast, the individual perception of differences between parties increases turnout because more citizens can find a party that is close to their own position and identify others as being further away. These opposite effects are possible because party-system polarization leads only some individuals to perceive differences between parties but leads others to avoid the emotionalized political arena. Moreover, individuals' ability to recognize differences between parties is not necessarily a consequence of party-system polarization. The contradictory findings in previous research are due to a conceptual and empirical blurring of these two essentially different aspects.

Faced with rising levels of cross-border migration, many countries have extended local voting rights to non-citizen residents. However, empirical evidence indicates that voter turnout among non-naturalized immigrants is lower when compared to citizens. This raises the question of how to explain this difference. A common answer is that the low turnout rates of non-citizen residents are primarily due to the socio-economic composition of this group and the challenges involved in adapting to a new political system. An alternative but less discussed possibility is that the low turnout concerns the nature of the elections. Hence, we examine whether the turnout of non-citizens is hampered because they are only allowed to partake in local elections. Based on a regression discontinuity design (RDD) using Swedish administrative data, we find that turnout could increase by 10–20 percentage points if the voting rights of non-citizens were extended to the national level.

In new democracies, what is the role of nationalism in terms of democratic behavior such as voter turnout? Previous studies have found that, in Western democracies, constructive national pride increases voter turnout, while blind national pride decreases it. However, little scholarly attention has been paid to new democracies. Given different political contexts, we argue that blind national pride can boost turnout in some new democracies that have lingering authoritarian legacies. Using the case of South Korea, we offer a theory about the relationship between blind national pride and voter turnout. We show that, in contrast to the West, blind national pride is positively associated with turnout in South Korea, and that the relationship appears more robust among both older cohorts, who experienced authoritarianism directly in the recent past, and those with conservative ideologies.

What is the relationship between feminism and political participation? How does partisanship moderate this relationship? Prior research shows that gender attitudes, particularly sexism, rather than gender identity per se, increasingly shape vote choice and participation in US elections. However, the role played by feminism in voter behaviour remains scarcely understood. As feminist identification crosses partisanship, we argue that its impact on engagement with campaigns and turnout depends on party ID. Therefore, we expect feminist identity and how it intersects with either aligned or conflicting partisan identity to impact partisans' participation asymmetrically. Using data from the 2016 and 2020 American National Election Studies, our results support these expectations. Holding the mutually reinforcing identities of Democrat and feminist has a significant mobilizing impact, while holding the cross-cutting identities of Republican and feminist tends to lead to a decline in political participation.

While there is considerable research on the role racial attitudes play in shaping white political preferences, relatively little is known about how racial attitudes influence white participation in democratic politics. We present a model examining the relationship between racial attitudes and political participation in the 2016, 2018, and 2020 U.S. national elections. Using a variety of measures of political participation, our analysis presents a clear finding: the direction of the relationship between latent conservative racial attitudes and political participation is asymmetrical among partisan sub-groups, with conservative racial attitudes motivating participation among white Republicans and, to a greater degree, depressing participation among white Democrats. This finding has stark implications for how racialized appeals are likely to be deployed in an era of increasing affective partisan polarization.

In many democracies, gender differences in voter turnout have narrowed or even reversed. Yet, it appears that women participate more in some circumstances and men in others. Here we study how life trajectories – specifically, marriage and having children – will impact male and female turnout differently, depending on household-level context. To this end, we leverage a unique administrative panel dataset from Italy, an established democracy where traditional family structures remain important. Our within-individual estimates show that marriage increases men's participation to women's higher pre-marital levels, particularly so in low-income families. We also find that infants depress maternal turnout, especially among more traditional families, whereas primary school children stimulate paternal turnout. Exploring aggregate-level consequences, we show that demographic trends in marriage and fertility have contributed to recent shifts in the gender composition of the electorate. Together, our results highlight the importance of the family as a variable in political analyses.

Does a universal basic income (UBI) affect voter turnout? This article argues that the introduction of an unconditional cash payment—where citizens receive money independent of employment status, age, or indigence—can have a turnout-enhancing effect. I evaluate the argument using the introduction of the Permanent Fund Dividend in Alaska. Differences-in-differences estimates covering November general elections from 1978 to 2000 provide compelling evidence that the Alaskan UBI has a significant positive effect on turnout. The results further suggest that the turnout increase was not a one-off effect but persists over a period of almost 20 years. Thus, a UBI has the potential to positively affect turnout among an entire electorate, adding to the discussion around potential welfare reforms in western democracies.

What are the electoral consequences of urban riots? We argue that riots highlight the economic and social problems suffered by those who participate, inducing potential electoral allies to mobilize. These allies can then punish local incumbents at the ballot box. We test this hypothesis with fine-grained geographic data that capture how exposure to the 2011 London riots changed vote choices in the subsequent 2012 mayoral election. We find that physical proximity to both riot locations and the homes of rioters raised turnout and reduced the vote for the incumbent Conservative mayor. These results are partly driven by a change in the turnout and vote choices of white residents. This provides support for the view that riots can help shift votes against incumbents who oppose the implied policy goals of rioters.

We document the effectiveness of automated (robo) calls for increasing voter participation in contrast to most published research which finds little or no effect from automated calls. We establish this finding in a large field experiment which mimics campaign behavior with a targeted, partisan get-out-the-vote campaign. Our findings show that across all treatments, automated calls led to three additional votes for every thousand subjects called during the 2014 midterm general election. Additionally, our experimental design allows for testing how the number of calls in a treatment, that is dosage, affects voter turnout. Here, results show that three extra calls increase the treatment effect to seven additional votes per thousand subjects called, but that too many additional calls decrease that effect to statistical insignificance in a six-call treatment.

The decision to vote is partly based on the expected cost of voting. We test the hypothesis that voting in one election reduces the expected cost of voting in the following election, as voters learn that the cost of voting is low. Using three different datasets—the National Electors Study conducted during the 2019 Canadian federal election; a two-wave YouGov survey in British Columbia and Quebec in 2008 and 2009, at the time of the federal and subsequent provincial elections; and a five-wave survey conducted for the Making Electoral Democracy Work project in Bavaria in 2013 and 2014, before and after the Land, federal and European elections—we find that voters who voted in a previous election perceive it will be easier to vote in a subsequent election. We also find evidence that voting leads to more accurate estimates of how little time it takes to vote.

Numerous studies conclude that declining turnout is harmful for democracy. However, we uncover the arguably positive effect that political parties become more responsive to the median voter in the election after turnout has decreased. We assume that parties are vote seeking and show that moderate voters are responsible for changes in turnout, and we argue that declining turnout in an election sends a clear signal to political parties that there is an opportunity to mobilize disaffected voters in the following election by responding to changes in public opinion. We report the results of statistical analyses on data from thirteen democracies from 1977 to 2018 that provide evidence that declining voter turnout in one inter-election period is associated with increasing party responsiveness to public opinion in the following period. Our findings have important implications for our understanding of voter turnout, political representation, and parties' election strategies.

Political campaigns frequently emphasize the material stakes at play in election outcomes to motivate participation. However, field-experimental academic work has given greater attention to other aspects of voters' decisions to participate despite theoretical models of turnout and substantial observational work signaling that a contest's perceived importance affects the propensity to vote. We identify two classes of treatments that may increase the material incentive to participate and test these messages in a large-scale placebo-controlled field experiment in which approximately 24,500 treatment letters were delivered during Connecticut's 2013 municipal elections. We find some evidence that these messages are effective in increasing participation, as well as that some of them may be more effective than typical nonpartisan get-out-the-vote appeals. While these results remain somewhat preliminary, our findings have important implications for our understanding of how voters decide whether to participate and how best to mobilize citizens who would otherwise sit out elections.

I examine the relationship between labor unions and voter turnout in the American states. Though it is well known that unions increase turnout directly, we know less about their indirect effects. Moreover, the indirect effects may consist of nonmember mobilization and aggregate strength. To examine the direct and indirect mechanisms, I analyze both state-level panel data and individual-level data with a multilevel approach. First, my panel analysis shows that unions are positively associated with turnout as expected. Yet, the association is observed only in midterm elections, but not in presidential elections. Second, more importantly, my individual-level analysis suggests that indirect nonmember mobilization and indirect aggregate strength are positively related to turnout, while direct member mobilization is not. The findings imply that the direct effects are limited and, thus, that decreasing levels of voter turnout due to recently declining union membership come primarily from indirect mobilization rather than direct mobilization.
